PLASTERlNG-TOOL.

SPECIFICATION forming part of Letters Patent N 0. 745,126, dated November 24, 1 903.

Application filed Tune 8, 1903. Serial No 160,660. (No model.)

To all whom it may concern.

Be it known that 1, WILLIAM A. WARSON, a citizen of the United States, residing at Seattie, in the con nty of King and State of Wash ington, have invented certain new and useful Improvements in Plastering-Tools; and I do hereby declare the following to be a full,clear,

and exact description of the inventi0n,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in plastering-trowels; andthe object in view'is the provision of mechanism for facilitating an pven distribution of plaster over a given surace.

With this and further objects in View the invention consists in combination, with a plate, of guiding-flanges carried thereby, a handle pivoted to said plate, a spring carried by said handle engaging the plate, and means for locking the handle to the plate.

It further consists in certain other novel constructions, combination, and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents an inverted perspective view of a trowel embodying the features of the present invention. Fig. 2 represents a top plan View of the same. Fig. 3 represents a view inside elevation of the same.

In the plastering art it is found that considerable experience is usually required before a workman is adept at the distribution of plaster evenly upon a wall, the quantity of plaster applied and pressure usually varying at different places, so that either too much plaster would be caused to pass between the 'laths or the coating of plaster be left too spaced studs, between which is carried a han- I dle 4, secured by means of a transverse pin 5, journaled in said studs. Extending transversely through the handle lisa rod or bar 6, which is locked against movement by a setscrew 7, threaded through said handle into contact with said bar. The ends of bar 6 carry, preferably, flat springs 8 8, which extend parallel to the handle, having their outer ends lying in a transverse plane preferably a considerable distance forward of the pivoted end of said handle, a transverse bar 9, connecting the free ends of said springs.

A latch 10 is pivotally carried by and preferably extends centrally through the handle 4:, and has its upper end normally pressed forwardly by means of a spring 11, the head 12 of said latch 10 being positioned to engage the edge of plate 1 a notch 13 being formed in the said platefor accommodating said latch, whereby in operation the handle may be locked in contact with the plate 1.

A guard 14 is fixed to the handle 4 transversely thereof just in the rear of latch 10 and designed when the handle is secured to the plate 1 by means of the said latch engaging the edge of said plate to lie in contact with the rear end of said plate and extend above the same for preventing the falling of plaster from the trowel during the initial lifting of the same.

In operation the operator grasps the handle 4. and passes the trowel into the plaster to be applied, using the same as a scoop, and when a sufficient quantity has been secured the trowel is lifted and applied to the wall, the operator having just before applying the plaster to the wall tripped the latch 10, so as to permit the parts to assume the position indicated in Fig. 3. The gages 2 are caused to contact with the laths,and the trowel is moved over the surface in the usual manner, the,

thickness of the plaster being positively determined by the width of the gages 2, said gages being of such comparativelythin material as to make an almost inappreciable line which may be easily smoothed over.

In the application of plaster in the manner described by the present improved trowel it will be observed that the gages? serve positively to govern the thickness of the coating applied while the springs 8 effect an equalization of pressure and prevent too great a quantity of plaster being forced between the laths when a new charge is first applied.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, the combination with a plate, of a handle pivoted centrally thereto, parallel springs carried thereby and extending beyond the pivoted end of said handle and connected to said plate and a transverse bar connecting the ends of said springs.

2. In a device of the character described, the combination with a plate of a handle pivoted thereto upon one side, parallel cushions interposed between said handle and the side of the plate to which said handle is secured, and means for making the connection between the handle and plate rigid.

3. In a device of the class described, the combination with a plate, of a handle pivoted thereto, a rod extending transversely of and connected to said handle, means for looking said rod against movement, and springs carried by said rod engaging said plate.

4. In a device of the class described, the combination with a plate and a pivoted handle connected therewith, governing means for said handle, of gage-flanges extending from the edges of said plate.

5. In a device of the class described, the combination with a plate, of a handle connected thereto, parallel springs carried by said handle engaging said plate and a swinging latch member carried by the handle and adapted to engage the plate.

6. In a device of the class described, the combination with a plate, of a handle pivotally connected therewith, parallel flat springs carried by said handle with their free ends engaging said plate, and a bar connecting the said springs.

7. In a device of the class described, the combination with a plate, of a handle connected therewith, cushioning means interposed between said handle and plate, means for locking the handle to the plate, and a guard carried by said handle and designed to extend past the plate when the parts are locked together.

8. In a device of the class described, the combination with a plate of a handle pivotally connected therewith, a guard carried by said handle transversely thereof, and means for locking said plate and handle together.

In testimony whereof I hereunto aiiix my signature in presence of two Witnesses.

WILLIAM A. WARSON.
